Abstract: The traditional single aperture antenna can only schedule the task in time, but the large loss rate easily appear when the task is more. Under the condition of dynamic aperture segmentation, the task management and execution of the antenna can be carried out in two dimensions of time and aperture, and it is easier to complete the task. In this paper, the characteristics of the dynamic aperture segmentation task is first analyzed and the resource management problem is proposed under the condition of two-dimensional time and aperture after introducing the rectangular layout idea in mechanical engineering. The data structure is then designed and the resource scheduling method of radar-communication integrated system is proposed based on the update rules of first in first out. Simulation results show that the algorithm has lower task loss rate and higher resource utilization ratio.
